Connecting 4DIX in voltage mode to IQ3

linked for voltage
4DIX in voltage mode
It is recommended to use SET (software tool) for configuring the controller. SET is supplied with 4DIX
strategy blocks for IQ1, IQ2, and IQ3 controllers; the strategy is described in the 4DIX data sheet.
If the SET strategy block is used it will set up both sensor scaling and strategy modules
(a) Sensor scaling:
For all IQ2 series controllers with firmware version 2.1 or greater, or IQ3 series controllers, the
appropriate SET Unique Sensor Reference from the following should be used:
Voltage (V) mode:
4DiXV
Current (I) mode:
4DiXI
If not using SET, use sensor type scaling mode 5, characterise, with the appropriate scaling from
the table below for all IQ2 series controllers of firmware version 2.1 or greater or IQ3 controllers; for
all other IQ controllers see Sensor Scaling Reference Card TB100521A.
Connect signal, 0 V, and screen to
controller as described above
(b) Strategy: The strategy must be set up to decode the digital status from the analogue input. The
SET 4DIX strategy blocks can be used as examples.
